ATTACHMENT FOR PHONOGRAPHS SPECIFICATION forming part of Letters PatentNo. 466,922, dated January 12, 1892.

Application filed December 29, 1890- tlerial No. 376,057. (No model.) 1

T aZZ. whom it may concern.-

Be it known that I, JOHN F. OTT, a citizen of the United States, residing in Orange, county of Essex, and State of New Jersey, have invented a certain new and useful Improvement in Attachments for Phonographs, of which the following is'a specification.

My invention relates to means for returnin g the reproducer of a phonograph to the endof the phonogram-blank at which the record commences, and is especially adapted to that class of phonographs the use of which is controlled by a nickel or other coin or token.

The invention consists in the apparatus hereinafter described for accomplishing the object above mentioned.

1n the accompanying drawings, which illusfrate the apparatus, Figure 1 is a plan view of the attachment. Fig. 2 is a View at right angles thereto. Fig. 3 is a side view of the coin-passage and the coin-controlled devices, a part of the coin-passage being broken away. Fig.4 is aview looking in the same direction, the coin-passage and several other parts being omitted; and Fig. 5 is a detail View of the coin-releasing lever or trip.

It is common in phonographs to have a fine screw driven by an electrical or other motor to move the reproducer slowly along the phonogram-blank at the same time that the blank rotates and to have a second screw of greater pitch and rotating in an opposite direction or having an oppositely inclined screw-thread for rapidly returning the reproducer to the beginning of the phonogram. In the present device the returning-screw is preferably not rotated by the phonographmotor, as is usual, but by a hand-crank 1, the shaft of which is journaled in suitable bearings in the frame 2. This shaft is provided with a gear-wheel 3, engaging with wheel 4 on the return-screw 5, which preferably has a left-hand screw-thread. On the shaft, also, and having a frictional connection therewith are two arms or links 6 6, in which the screw 5 is supported. At the left end of screw 5 is a smooth wheel 7,-on which spring 8 bears for the purpose of producing resistance to the rotation of said screw. On the link which carries this spring is mounted a projecting lug 9, which when the apparatus is at rest is below the extension 10 on the spring-pressed pivoted lever 11, but when the apparatus is '28 is the motor-battery.

being used is raised above said extension and is held up thereby.

The arm or link 6 is provided with an extension 12, which in turn has an angle-extension 13, one end of which is beveled, as indicated at 14. A catch normally engages with 13 and holds it and link 6 from movement. Said catch is rigidly mounted on an axle 16, at the opposite end of which is an arm 17, having a cam-shaped end extending into the coinpassage of the tube 18, which tube communicat-es with the coin-receiving slit 19. This is clearly shown in Fig. 3.

is a spring which normally holds 15 and 17 in their forward position.

21 is an angle-lever pivoted at 22 and having a bent end 23, extending into the coin-passage just below the cam-shaped end of 17. (See Fig. 3.) A plan of this lever is shown in Fig. 1. Under the outer end ofsaid lever is a post 24, carried by the extension of the movable link 6'. I

In Fig. 1, 25 indicates the ordinary feed screw of a phonograph, driven, preferably, by an electric motor, and 26 is the feed-arm or other feeding device, connected with the reproducer in the ordinary manner. 27is the phonograph-motor. (Shown diagrammatically.) One terminal of the circuit is connected to a platinum or other conducting plate 29, which is mounted on but insulated from the frame, and the other ter minal is connected to the pivoted lever 30. At the opposite end of the frame is a second pivoted lever 31. 32 is a rod connecting levers and 31. 33 is an arm carried by the feedarm and adapted to strike lever 31 as it moves toward the right and tostrike lever 30 as it moves toward the left.

The apparatus above described is operated in the following manner: The feed-arm being at the extreme right of the screw, as indicated in Fig. 1, when it is desired to move said arm and the reproducer toward the left, a coi1'1 for example, a nickel-is dropped into the coin-passage, and as it falls it strikes the cam-face of the pivoted arm 17, and the weight and size of the coin are such that it presses arm 17 and at the same time arm 15 toward the right. The coin comes to rest in position to hold the arm 17 in its retracted position, the coin resting on the end 23 of. the arm 21. As the crank is turned by the hand the screw strikes the pivoted lever 11, moving it'back against the force of its spring, thereby moving the projection 10 from under lug 9 and allowing the screw to resume its normal position. The upward movement of the screw above describedraised'post 24 against the outerend offthe pivoted lever 21, thereby withdrawing the end 23 from the coin-passage, allowingthe coin to fall into a suitable receptacle- When.

the screw is released and returns to its normal position, as above described, the beveled face 14 of the extension 13 ridesovertheinclinedend of the catch.15 and the parts resumethe position shown in Fig.4. henthe apparatus is in theposition shown in Fig- 1, the motor-circuit is open. WVhen the arm33 reaches its extreme position toward the left, it carries lever 30 of thecircuit-controlleronto plate 29', closing the circuit. Thecircuit remains closed until the arm 33fmoves backto its-.first' position, when the circuitv is again opened. 7

Itjwill be evident that the partstmay be variedin form to a considerable extent, and? I do not confine myself to the exact'construction described and shown.

The combination, with the feed-screw for advancing the reprod'ucer of a phonograph, of a return-screw for the. reproducer, normally outof'engagementjwith the feed-arm, and a coin-operating device controlling the movementofifsaid return-screw toward'said feedarm, substantially as described.
